9/11 Airplane Video Compositing & Luma Key Theory DEBUNKED!



 By Mark Conlon

In this analysis I’m going to explore Ace Baker's theory he proposes in his blogspot article video he published on the 27th May 2008, entitled - "Theory of Live 9/11 Airplanes Composites" and also in a later version which he included in his 2012 film entitled - "9/11 The Great American Psy-Opera". They both explain how he believes video compositing was used on 9/11 to "insert" in real-time, a flying airplane into the Fox News "Chopper 5" video. I will primarily be focusing my analysis on his later film - Chapter 7, called "The Key" from "9/11 The Great American Psy-Oprah".





See below: Ace Baker's Theory of Live 9/11 Airplane Composites video:


In Ace Baker's 2012 film 'The 9/11 The Great American Psy-Opera' - Chapter 7 "The Key", he explains how he believes a "fake" airplane was "inserted" into the Fox News "Chopper 5" footage using live video compositing layering techniques and "Luma Keying".


Ace Baker also explains what went wrong with the infamous "nose-out" anomaly captured in the Fox News "Chopper 5" video footage, as (Flight 175) plane's nose "exits" the South Tower building still "intact", which is physically impossibly. See below: The famous "nose-out" shot...


While I do agree that it is a physical impossibility for the plane's nose to exit the South Tower building with it's nose still "intact", I do NOT agree with Ace Baker's explanation of this impossible anomaly captured in the Fox News video footage, because of the "technical issue" which Ace Baker has chosen to "omit" which makes his explanation invalid.  

So we can thoroughly understand why the "technical issue" arises, which makes his theory invalid, I will first briefly explain Ace Baker's "theory". 

Firstly, Ace Baker proposes that there are some "necessary"attributes which would make live video compositing possible and allow the insertion of a "fake", computer animated, airplane into the live video.
 
The attributes are:
  • High contrast between tower and sky
  • Steady camera with no panning, tilting, or zooming
  • Airplane path is across sky only
  • Airplane disappears across straight vertical edge
  • "Impact" wall is hidden
  • No shadows required  
Ace states that, "Absent any one of these attributes, inserting a "fake" airplane becomes "impossible".

See short video excerpt below from Ace Baker's film explaining Compositing,  Layering and Luma keying.


Now we are familiar and understand Ace Baker's theory and explanation he proposes in his film of how they "inserted" a fake airplane into the Fox News "Chopper 5" video, we can look at the "technical issue" which makes his theory invalid. 

Technical Issue Explained...
The "technical issue" in Ace Baker's theory is the use of a "Luma Key" for the purpose of adding a "fake" plane into the live video footage, which cannot be reproduced as seen in the live Fox News "Chopper 5" video footage of the 2nd plane impact. The technical issue proves that "Luma Key" was NOT used in the live Fox News "Chopper5" footage as Ace Baker has "alleged". Please refer to the images below as I continue to explain the technical issues. 



If a Luma Key had been used in the live Fox News "Chopper 5" video, the exiting "nose" of the alleged "inserted" fake airplane in the 2nd (middle) composited layer would be "visible" on top of (and in front of) the "explosion" exiting the tower which is the 3rd (bottom) layer, which is the "original" Fox News video.

 
The reason for this is, the "Luma Key" works off of the luminance (brightness) within the video signal. In order to see an airplane animation that has been sandwiched in between two duplicate layers of video from the same camera feed (3 layers altogether), the (top) 1st layer would require portions of the image to be cut out, revealing the added airplane layer underneath in the 2nd (middle) layer. When this is done using a "Luma Key", a predetermined luminance (brightness) threshold (limit) is set which will prevent any portion of the video image from showing that is brighter than that brightness threshold setting, making those brighter portions disappear completely, and in this case, the brightness threshold would have to be set to a point where it would eliminate the entire sky background (of the 1st (top) layer only) while leaving the darker Twin Towers intact to act as the mask for the plane to disappear behind.


The biggest issue here is that the explosion that erupts from the opposite side of the South Tower, is as bright as the sky threshold Luma Key setting, which means that the explosion would "disappear" just as the sky does because of "Luma Key" threshold setting on that 1st (top) layer, which would reveal the 2nd layer behind it which supposedly contains the fake "inserted" plane and it's protruding nose. Which should've looked like this image below:



The fact that the explosion does "NOT" disappear, and we observe it covering and obscuring the plane's "nose", is conclusive proof that a "Luma Key" was not used in the Fox News "Chopper 5" video footage

Below: is a video made by someone who goes under the name "saultrain". He explains "excellently" far better than I can why the South Tower explosion should "disappear" in the Fox News "Chopper 5" video footage if a "Luma Key" was used to "insert" a fake plane using compositing and layering. The fact the explosion didn't disappear in the news footage demonstrates thoroughly that Ace Baker's "Luma Key" theory is invalid.

This case is now closed...

In Search of United Airlines ‘Flight 175’

Image
By Mark Conlon I would like to begin by thanking Julia Ratsey and Conspiracy Cuber for their help towards this blog post. Also thanks to Andrew Johnson, Richard D. Hall and Chris Hampton who have been supportive of my research.   United Airlines “Flight 175” (UAL 175) was a scheduled domestic passenger flight from Logan International Airport, in Boston, Massachusetts, to Los Angeles International Airport, in Los Angeles, California. On September 11 th 2001 UAL 175 was scheduled to depart at 08:00 a.m. for Los Angeles. Allegedly fifty-one passengers and the five hijackers boarded the 767 through Terminal C's Gate 19. The plane pushed back at 07:58 a.m. and took off at 08:14 a.m. from runway 9. It is estimated that UAL 175 was hijacked between 08:42 a.m. and 08:46 a.m. while American Airlines “Flight 11” (AAL 11) was just minutes away from hitting the North Tower. We are told the hijackers forcibly breached the cockpit and overpowered the pilot and first officer, allowing lead hijac...

Who Is 9/11 Harley Guy..? "Seeing Through The Disinformation"

Image
  By Mark Conlon   Much has been made in recent years of the use of "crisis actors" involved in relation to 9/11 and a number of " staged " terrorist attacks that followed. Much of the early promotion of "crisis actors" originated and was heavily promoted by Simon Shack, along with other so-called 9/11 researchers'.  One of the most famous 9/11 cases was the "Harley Guy" on Fox News who gave an account of the " official " 9/11 WTC building collapse story from the get-go, or did he? There has been many people who believe the "Harley Guy" to be actor Mark Adrian Humphries. Of course Mark Humphries denies any involvement on 9/11, and claims he was in Los Angeles at the time the 9/11 events were happening. See image below: Taken from Simon Shack's - September Clues forum.  So who is the "Harley Guy"? I still see and hear people accusing Mark Humphries of being the "Harley Guy". From research which doesn...

Flight 175 and The Truth about 'The Truth in 7 Minutes' in FIVE Minutes

Image
By: Mark Conlon - 25 Jan 2014   (Updated 24 Feb 2017) Short introduction and note by Andrew Johnson [ADJ] Below, Mark has carefully documented some further errors made by Markus Allen in a recent response to another error he made in an earlier video. The thrust of what Markus Allen appears to be trying to say is that “the videos of Flight 175 crashing into the WTC are fake”. This, of course, has been a topic much discussed on 9/11 “truth” websites. I have come to the conclusion, partly because of what I have covered in this article, that there has been a deliberate attempt to promote the 9/11 video fakery position in order to obscure or cover up the knowledge of the use of some type of image projection technology, which was used to create a very powerful illusion of plane crashes (for those chuckling about this idea, simply try and account for the physical evidence that plane wings cannot cut through steel box-girders and also account for the fact that some witnesses did not see or...
